15 Cool and Casual Christmas Party Outfits

Not all Christmas parties require black tie attire, so for now, pack away your fancy dress until your annual family Christmas dinner rolls around. Casual holiday gatherings have no set dress code—just show up in something festive (a given) and comfortable, and get ready to sit next to the fire, sip on some hot chocolate, and indulge in some sweet treats surrounded by your closest friends and family.

If you need some advice on exactly what makes a great casual Christmas party outfit, let's break it down. As mentioned before, there are no set rules to follow, so allow yourself to get creative and wear something that's uniquely you. Of course, it never hurts to wear pieces rendered in two festive colors—red and green. Or maybe even an ugly sweater. The possibles are endless!

Ahead, get some ideas of casual Christmas party outfits with our roundup of fashion girl–approved looks that are cool, festive, and, most important, super easy to emulate.
